You're reading things that aren't there. Literally no-one has argued Vietnam or its people are rich (or even suggested anything close to it). No one.
Recap: The commentator you replied to said it's gotten better in the best decade (factually correct) and suggested it's considerably better than most Westerners think it is (an opinion/observation that also correlates with my experience, but YMMV).
From that comment, you brought up flooding in Saigon to which it was pointed out (to illustrate the absurdity of even bringing it up), that one of the richest cities in the world also has parts of it that flood.
You took that to mean they think Vietnam is wealthier than Japan (?) and that flooding is worse in Tokyo (?). No one said either of those things.
Look, you seem articulate and intelligent but no-one has even come close to saying what you keep suggesting. Please re-read the thread with a less combative mindset and realize we are all pretty much in agreement.
